My invention relates to machines for inserting fastenings in such Work shoes, it being especially applicable to those machines by which heels are attached by nails driven from within the 35; shoes.

In apparatus of the character above mentioned,

to operate upon Work of `diilerent sizes, it is a common practice to provide for the insertion of the attaching nails at different distances fromr 10i the rand-crease, this being accomplished by adjusting toward and from the central vertical axis of the jack upon which the Work is supported tubes containing the nail-drivers. lt is also customary, when a loading device is employed to transfer the nails from a point oi supply to a jack, to alter the nail-holding passages oi said device by supplying different loader-blocks to correspond to the particular nailing design for which the jack is arranged.

An object of my invention is to obtain a change z gppart of the operator. To bring this about, I comfj bine` with a jack or work-support a loader or transferring device traveling between a nailre ceiving position and a nail-delivering position atl the Work-support and provided with movable rezfholding members, in which are passages for nails or other fastenings to be inserted, together with automatic means for moving the members upon the transferring device. Preferably, this movement is effected by contact with elements of the afsupport, as `by engagement oi the nail-holders upon the loader with tubes variable in `location upon the jack, the movement oi the holders being resisted bysprings Whichurge them tc normal positions. Each holder of the nail-supplying agjcsystem, Whether or not it be an element oi they "loader, may have a nail-retaining member extending into its nail-passage and being movable to free the nails. As illustrated, the retaining members are moved similarly to the holders, cnacting to free the supported nails by contact with m"an element of the jack. By this arrangement, the loader may be caused to receive in the passages nails from a supplying means, such as the footplate of a distributor, in an unvarying relation; .'iiiand then, as the loader travels into direct cooperation with the jack, its holders, by successive contact with the nail-receiving tubes of said jack, are retained in registration therewith, the holders being automatically brought into conformity with Slthe jack-tubes, and the nails released from the (orV 1432)" retaining members to enter said'tubes. Since the nailing designs are of different dimensions transvers'ely of the jack as Well as from front to rear, certain of the holders are mounted upon the loader for both bodily and angular movement. 60 In the presentinstance, those holders having suchacompound' movement are each provided Withan inclined contact-surface, which, upon engagement with a nail-receiving member or jackrtubapr'odu'ces the desired angular move- 65 ment, viinal registration with the tube being eflectedby a surface upon the holder in which the inclined surface terminates. Apart from the manner of cci-operation with the work-support or jack, patent'able novelty is believed to exist in 70 i cfertainjaspects of the nail-loader per se, as one in-Which 'nail-holding members are yieldably urged to normal positions, so they are capable of adapting themselves to different nailing designs. The preferred lmanner of attaining this con- 75., formity is byarrangingcertain of the holders,v as those for the breast and rear nails, to slide upon thebody-portion ofthe loader, While others, as

those forjthej side nails, are pivoted upon slides.

Movable shutters projecting into the passages of 80 rI his not only causes the rear nail driven into the 9a,

heelseat of a. jacked shoe as through a. vertical tub'eto enter, thel heel to be attached at an inwardincl-ination, soit is less likely to emerge throughy the rear Wall when the heel is tapered heavily from the heel-seat-end to the tread-end, 9v but alsoisparticularly adapted for coi-operation with the loading or transferring mechanism previously outlined and in which delivery-openings of the nail-holders `occupy a plane similarly inclined. Whentheseinstrumentalities are brought 10 together, the holders of the loadermay pass freely over the portions of the jack-top in which are openings with-which theyare not to register, and reach, without interference, the openings to which they are to deliver.

`In the accompanying' drawings is illustrated one of several possible formsof my invention. Here,

At 10 (Figs. 1 and 11) appears the body of a jack designated `Aas a whole by J and adapted for the inside nailing of heels. Generally it may be arranged as is that of Letters Patent of the United States N0. 1,545,575, Standish, July 14, 1925. That is, it contains a reciprocatory plunger 12 carrying nail-drivers 14 operating in tubes shown as ve in number, there being two breasttubes 18, 18 formed as a unit, two side tubes 20, 20, and one rear tube 22. In these tubes heel-attaching nails may be held resting upon the ends of the drivers. The tubes are variable in position toward and from each other in the manner described in previously mentioned Letters Patent, a screw 23 being used to move a cam-plate 25 and thereby adjust simultaneously all but the rear tube, this beingclamped separately. Of course, any other desired adjustment may be employed. The tubes may thus be arranged in accordance To obtain a close crease, it is desirable to locate the points of insertion of the nails close to the peripheries of the heels, and as the extreme pitch oi many heels in womens work tends to cause the rear nails to emerge through the side walls, many heels are thus spoiled. I therefore'prefer to incline at 24 the surfaces of the upper ends of the jack-tubes which contact with the heel-seat of the shoe to be heeled, the inclination being generally in a plane diverging downwardly from the horizontal from front to rear ofthe jack. The breast and side tubes may also have their surfaces 24 laterally inclined, downwardly and outwardly. This not only directs the nails inwardly away from the heel-wall, but also makes the tread-surface of the heel more nearly horizontal, giving more effective engagement therewith of the usual pressure-abutment which resists the nail-driving forces. To hold up the forepart of a shoe being heeled, so the heel-seat may contact evenlywith the inclined tube-ends, a rest 26 is provided, this being au'justably pivoted at 28 upon a vertically movable slide 30 secured to the front of the jack by a slot-and-screw connection 32. The rest may,

by its connecting means, be varied in position both as to height and inclination.

' The attaching nails may besupplied to the jack by loadingmec'hanism L, of which only the Iforward portion is illustrated herein. This mecha- 'nism has VVa horizontal recipro'catory slide 36 carrying at its end toward the jack a frame 3'8 to receive a loader-block 40 in which are contained the nails for delivery to the jack J, in a manner which will be later explained. Delivery to the loader is made from a foot-plate 42 (Fig. 2) through passages in which nails are fed in successive groups by way of tubes 44 leading from a distributor (not shown). The loader-block containing the nails may be carried from its receiving position beneath the foot-plate to its deliver,- ing position over the jack-tubes and reversely by such a mechanism as is described in Letters Patent of the United States No. 1,785,928, Benjamin, December 23, 1930, and which is under the control of the operator.

The loader-block 40 has projecting from the opposite sides of its upper portion flanges 46 resting upon the frame 38 (Fig. 10), it being releasably held against upward displacement by latches 48, 48 (Fig. 3) secured to it and engaging the under side of the frame. The block or bodyportion has extending through its forward eX- tremity a wide slot 50 while at the rear is a narrow central slot 52 and two parallel side slots 54, 54. The end of the slot 50 is closed by a retaining oar 56 and the rear slots are similarly closed by a bar 58, both of these bars being secured to the ends of the block. Movable in the slot 50 is a holder 60 for the two breast-nails. This holder is in the form of a slide having guide-hanges 62 extending above and below the block. From the body of the slide rises a portion 64 containing, together with the slide, vertical passages 66, 66 for the breast-nails,'these being preferably in unvarying relation to each other. The upper extremities of the holder-passages may have somewhat enlarged throats 68 to facilitate the introduction of the nails, and, to permit close approach for nail-delivery, the holder-wall about the lower ends of the passages is inclined at 70 vto correspond to the inclination of the jack-tubes at 24. The delivery-portions of the associated holders are similarly formed. The slide 60 is held normally forward, to an extent permitted by its contact with the bar 56, by a helical spring 72 (Figs. 4, 6 and 7) contained within a recess in it and in an alined recess in an. opposed surface of the block 40. To hold the nails in each passage until, because of registration between said passage and a jack-tube, they are ready for delivery, each passage is provided with a movable retaining member or shutter 74, preferably furnished by a projection from the lower edge of a movable carrier-plate '76 which may be guided by arms 75, '75 (Figs. 3 and l2) extending toward the front of the plate and movable in slots 77 (Fig. 10) in opposite sides of the holder 60. The carrier-portion of the shutter has an upward extension '78 which is supported by a screw 80 upon the holderportion 64 to move in a recess therein. This movement allows the projections 74 to either extend into the corresponding passages 66 to support the contained nails, or to be shifted rearwardly to free said nails for delivery to the jacktubes 18. The carrier-plate is shown as urged yieldably toward the iront of the loader by a spring 82, interposed between the head of a screw 83 threaded into the plate and the end of a counter-bore in the holder 60 in which said screw-head is movable. Both retaining projections 74 are shifted within the passages 56 to release the nails by the engagement of a projection 84 depending from the center of the plate 76 and contacting with a wall 86 between the jack-tubes 18, 18. This Contact occurs when the Slide 36 brings forward the loader-block 40 with its contained nails. After the shutters have been opened, the holder 60 may yield, compressing the spring 72. The manner in which the loaderpassages, register with. the `jack-tubes and of release of the nails fromthe passages will be stated in greater detail after the arrangement of the rear and side nail-holders of the loader has .been described.

In the center rearslot 52 in the block 40 a holder 9.0 for the rear nail is movable (Figs. 4 and 8). This, like the holder 60, consists of a slide having guide-flanges 92 contacting with opposite sides of the block and under the influence of a springV 93, similar to the breast-slide-spring '72, by which it is urged inwardly. The outer extremity of the spring 93 may be received `byfia. recess in the bar 58. The holder contains in it and in an upward extension 94 a nail-receiving passage 96, normally closed at its lower extremity by a retaining projection 98. The projection is formed upon a shutter-body or slide 99 arranged to reciprocate in a horizontal bore at the bottom of the holder. It is forced yieldably forward into the passage 96 by a spring 100 contained in a recess within the slide and backed by a screw 102 threaded into the holder. A pin 104 lying in a slot in the holder limits the forward travel of the shutter. A Wall 106 of the shutter strikes the rear of the jack-tube 22 when vthe loader travels forward, opening the shutter against the force of the spring to release the nail. This is followed by the yield of the slide `90 against the spring 93. f

While for the breast-nail-holder and rear nailholder only rectilinear movement from front to rear of the loader-block is necessary, the side nails must also be varied in position laterally to allow them to conform to diierent designs. The two side holders 108, 108 and their carrying means may be the same, except that their lateral movement is opposite. Consequently, but one will be described. Movable in each loader-block-slot 54 is a. holder-slide 110 forced normally forward by a spring 112 interposed between it and the bar 58. Rotatable in the forward extremity of the slide is a vertical spindle 114 (Fig. 5) ,i and clamped against movement about the upper end of the spindle is a horizontal arm 116 of the holder 108, in which arm is avnail-receiving passage 118. `Formed upon the `holder at the outer side of the passage yis a contact-arm 120 provided with an inner vertical surface or wall 122 inclined outwardly and forwardly from the direction of movement of the slide 110 (Figs. 3 and 9). At its inner end the wall 122 terminates in a curved Wall 124 lying transversely of the path of the slide. Projecting through the wall 124 into passage 118 is the nail-retaining portion 126 of a sliding shutter 128. The construction and operation of this shutter may be identical with that of the rear holder 94 and needs no further explanation. A scissors-spring 130 is shown joining the arms 116 to` urge them normally toward each other. As the loader-block moves into co-operation with the jack J each surface 122 will strike one of the jack-tubes 20, whatever may be the adjustment of said tube, turning` the holder 108 outwardly about the axis of the spindle. When a wall 132 (Fig. 5) of the shutter 128 reaches the jack-tube, it contacts therewith to open said shutter and release the nail. Finally, upon completion of the shuttermovement, the curved surface 12.4 strikes the tube the slide 110 then -yielding against the spring 112.'. vIt will thus be seen that there; is ima parted to each passage 118 a compound angular and rectilinear movement, which permits. it to adapt itself to different side-nail locations both longitudinally of the heel-seat and transversely thereof. i

Fig. 2 of the drawings shows the loader L in its nail-receiving position beneath the footplate 42 of` the distributor, while in Figs. 1, 3, 4, and 10 the elements are positioned as when in direct co-operation with the jack J for delivering the nails to the tubes thereof. The foot.- plai-e-passages have an unvarying relation and the nail-holder passages of the i loader-block 40 register with these whenever a load of nails is received, regardless of the adjustmentof the jack-tubes for different nailing designs. This normal foot-plateand loader-block-passage arrangement may be such that, of the latter, the breast-passages 66, 66 correspond to the maximum design or are most widely separated from the center of the group, while the passages 96 and 118, 118 are in accordance with the minimum. design to be nailed. `The breast-holder 60 is: maintained by the spring '72, the rear holder 90 by the spring93, and the side holders 1.08, 108 by the springs 112 and 130 to thus locate the passages.` Assume that a heel is to be attached calling for the employment of the smallest nailing design, and that the loader-block 40 is beneath the foot-plate 42, having received therefrom a load of nails which rest heads down upon the retaining projections 74, 98 and 126 of theshutters. Before the operator places a shoe upon the jack J and applies thereto the heel to` be attached, he causes the loading mechanism to advance from its receiving position in the manner described in the Benjamin patent. When it, reaches the jack, the lower portions of the holder 60, including the depending shutter-projection 84, pass freely over the jack-tubes 20 and 22 because of the downward inclination o-f these from front to rear of the jack. The projection 84.con.` tacts, however, with the wall 86 of the breast-v section of the jack and causes the shutter 76 to be forced back, the spring 82 yielding (Fig. 7). When the loader-passages 66 have come sufficiently into registration with the jack-tubes 18, this action will have vwithdrawn the retaining projections 74 from beneath the nails which they support to release said nails and permit; them to drop into the tubes 18, where they rest upon drivers 14 ready for insertion. The forward travel of the loader-block continues, compression of the spring 72 allowing this, the holder being maintained stationary by the engagement of its shutter with the jack-wall 86. In this loader movement the side holders 90 pass the rear jack-tube 22 without interference and the walls 122 of the holder-arms 120 contact with the jack-tubes 20. This causes each side holder to move somewhat outwardly, turning about the axis of the spindle 114 until the shutter-Wall 132; strikes the jack-tube. The shutter 128 is then` displaced against its spring to withdraw the. nail-retaining projection 126 from the cor-responding passage 118 and discharge the supported nail into the jack-tube (Fig. 9). Further forward movement of the loader-block is made possible by the yield of both the springs 72 and` 112. Contact of the wall 106 upon the shutter 99 with the rear jack-tube 22 releases the contained nail from the loader-passage 96,` to enter said tube (Fig. 4) and the loading operation is;

completed. Forward travel of the loader,A how-15gL lll miV

lldevice movable `from a fastv means for moving the member,

ever, is continued sufficiently to compress the spring 93, ensuring full alinement of the passage 96 with the jack-tube. The loader-block is thereupon withdrawn by its slide 36 from above the jack to beneath the foot-plate 42. When the holders with their nail-retaining means leave the jack-tubes, their springs restore said holders and retaining means to their initial positions, and the mechanism is ready to receive and deliver another load of nails to the jack. In the case of the smallest nailing just considered, the movement of the breast-nail-holder is from its normal position of maximum displacement from the center of' the group of holders to the rninimum necessary to bring it into conformity with the chosen nailing design. The associated side and rear tubes, however, normally correspond to this minimum arrangement and their displacement by contact with the jack-tubes is merely to insure perfect registration of all the holderpassages With the jack-tube-passages. Taking the opposite extreme, or the actuation of the holders of the loader for delivery to the maximum nailing design, the breast-holder is now moved but lslightly to establish registration with the jack-tubes, while the displacement of the side and rear tubes is through the maximum distance. In this way, travel of the loader in one direction for delivery is caused to adjust nail-holders which move in dilerent directions from a central point. For intermediate nailings, corresponding opposite movements of the breast-holder and the side and rear holders will be produced. Throughout the entire range, the action of the loading mechanism in adapting itself to diierent designs is entirely automatic, the holders receiving the nails from the distributor always in the same relation and then conforming to any adjustment which has been made at the jack-tubes.

While there is herein particularly disclosed only the automatic individual adjustment to different nailing designs of nail-holders associated with a loader, it is to be understood that my invention also comprehends a variation in the positions of jack-tubes to conform to diverse arrangements of nail-holders of a loader. Further, the adjustment of the loader nail-holders may be effected by a member common to all and manually.
